I call for the need of world leaders to address climate change and reduce the increasing risk of disasters- and world leaders must include mayors, townships and community leaders.

To achieve a Green Revolution, African farmers, must have access to land and security of tenure. They also need access to markets, technology and improved infrastructure.

Our atmosphere can't tell the difference between emissions from an Asian factory, the exhaust from a North American SUV, or deforestation in South America or Africa.

Now it is the least developed world who are not responsible for this climate change phenomenon that bore the brunt of climate change consequences so it is morally and politically correct that the developed world who made this climate change be responsible by providing financial support and technological support to these people.

I have been urging the leaders to listen to the aspirations and challenges of their own people, and engage in dialogue and take very bold measures. Normally, to their regret, these measures and bold reforms come too late, too little.

Since problems spill across borders, security anywhere depends on sustainable development everywhere.

A deal must include an equitable global governance structure. All countries must have a voice in how resources are deployed and managed.
